Is it Covid, flu or RSV? Chart compares differences in symptoms

Covid, flu and respiratory syncytial virus (RSV) are together driving a national wave of respiratory illnesses.

Around 76{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} of U.S. hospital inpatient beds are full, according to data from the Department of Health and Human Services. Pediatric beds are at a similar level, though six states have 90{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} or more of their pediatric beds full, according to an NBC News analysis of HHS data.

Covid, flu and RSV can be difficult to distinguish, since they share many common symptoms. But it’s useful to know which virus you have, since that determines the treatments you should receive and how long you should isolate.

Certain hallmarks — either symptoms or how the illness progresses — can help differentiate each virus. Here are five factors to consider.

Some symptoms are unique to particular viruses

A runny nose, cough, congestion or sore throat can arise because of any of the three viruses or a common cold. But a loss of taste and smell is more commonly associated with Covid than with flu or RSV. And wheezing is often a tell-tale sign of a serious RSV infection, usually found in kids or older adults.

The only way to know for certain, though, is to get tested.

“I don’t think anybody would ever go, ‘Hey, listen, I think you have a virus based on your symptoms,’ and feel confident to say what virus that is,” said Dr. Frank Esper, a pediatric infectious disease specialist at Cleveland Clinic.

Are symptoms coming on gradually or all of a sudden?

Flu symptoms tend to develop more suddenly than those of Covid or RSV.

“Flu classically comes on with an abrupt fever first that happens pretty quickly. That’s somewhat contrasted by RSV and Covid, where we think of a slow escalation in symptoms,” said Dr. Scott Roberts, a Yale Medicine infectious disease specialist.

How long has it been since exposure?

The illnesses have different incubation periods — the time between exposure and symptoms. On average, flu symptoms tend to develop two days after exposure to the virus, whereas RSV symptoms tend to take around four to six days to appear, and Covid’s typical incubation is three to four days for the omicron variant.

“If I go to a party and I get symptoms the next day, it’s probably flu because that can be as short as 24 hours’ incubation period,” Roberts said.

Age makes a big difference in a disease’s symptoms and severity

RSV is unlikely to make a healthy adult feel very sick, whereas Covid and flu certainly can.

“In general, if you’re a young healthy adult or you’re not in an extreme of age, and you get pretty severe illness, it’s probably not RSV,” Roberts said.

The groups most vulnerable to severe RSV infections are babies, children with lung diseases, adults ages 65 and up and people with weakened immune systems.

Symptoms can also look different depending on your age and immune status. Many kids are encountering respiratory viruses for the first time this year as they return to regular schooling and socializing, so their bodies may have a harder time clearing the infection, which can lead to more wide-ranging symptoms.

According to Esper, almost a fourth of children have gastrointestinal symptoms (like diarrhea, stomach pain or vomiting) from viral infections. That’s less common in adults with seasonal flu or RSV.

People with weakened immune systems, meanwhile, are more likely to develop severe symptoms or pneumonia from any of the three viruses.

Consider which virus is circulating the most in your community

Disease experts anticipate that Covid cases will climb over the holidays as more people travel and gather indoors. Average daily cases reported to the Centers for Disease Control and Prevention have already risen nearly 11{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} over the last two weeks, according to NBC News’ tally.

But it’s difficult to determine local Covid transmission levels, since many people use at-home tests. RSV and flu tests, by contrast, are performed at a doctor’s office or ordered via prescription.

RSV infections seem to have passed their peak nationally. Although the CDC does not keep a national count of RSV cases, the number of positive weekly tests fell from more than 17,000 in the week ending Nov. 5 to around 9,000 in the week ending on Saturday.

By contrast, flu cases are skyrocketing. The national share of influenza tests that came back positive rose from around 8{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} in the week ending Oct. 30 to nearly 15{bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} in the week ending Nov. 13. Flu hospitalizations are the highest they’ve been at this time of year in more than a decade. 

Esper said he expects the Cleveland Clinic to be “swimming in flu” two weeks from now.

The picture varies by region, however. In the Northeast, Roberts said, “we saw RSV surge over the last one to two months and it’s actually plateaued — which is great news — and then flu, only the past few weeks we’re seeing an exponential rise.”

“The Southeast U.S. — Georgia, Alabama, Mississippi — they saw kind of the opposite. They saw initially a surge in flu, and then now you’re seeing RSV start to catch up,” he added.

Available treatments and vaccines

Unlike Covid and the flu, there are no vaccines or universally prescribed treatments for RSV.

“RSV scares me the most, probably, because you can’t do anything about it and so many young kids haven’t seen it. We’re really seeing record surges in our pediatric hospitals,” Roberts said.

To reduce the length of flu symptoms, though, doctors usually prescribe Tamiflu or one of three other approved treatments. For some people with Covid, doctors can prescribe Paxlovid.

Dr. Ashish Jha, the White House Covid-19 Response Coordinator, emphasized the benefits of getting flu shots and Covid boosters.

“In this moment where we have a lot of flu, still have a decent amount of RSV, still got a good amount of Covid, the single most important thing people need to do is go get vaccinated,” Jha said at a Tuesday briefing. “It keeps you out of the hospital.”

Hospitals hitting capacity from RSV, flu, covid and staffing shortages

Comment

When Christina Anderson’s mom started off owning upper body pains in October, they rushed to the nearest emergency space in their hometown of Ottumwa, Iowa. Because of her mother’s ovarian most cancers diagnosis, Anderson assumed they would be witnessed within just a sensible time. Instead, their excursion became a nine-hour odyssey.

“When we very first walked in, it was packed and compared with just about anything I have ever noticed,” Anderson explained. “I saw men and women laying throughout the chairs some slumped around who experienced been there for hrs in advance of we arrived, and some even received annoyed and remaining simply because they could not hold out any longer.”

Anderson’s tale is not an isolated episode. Patients nationwide are experiencing comparable ordeals.

Hospitals throughout the United States are overwhelmed. The mixture of a swarm of respiratory health problems (RSV, coronavirus, flu), staffing shortages and nursing property closures has sparked the condition of distress frequented upon the by now overburdened wellness-treatment technique. And professionals believe that the difficulty will deteriorate even more in coming months.

“This is not just an situation. This is a crisis,” stated Anne Klibanski, president and CEO of Mass Standard Brigham in Boston. “We are caring for patients in the hallways of our emergency departments. There is a enormous ability crisis, and it’s getting to be additional and a lot more difficult to acquire care of clients correctly and offer the greatest treatment that we all require to be furnishing.”

Along with a scarcity of beds, Klibanski reported her healthcare facility system is extremely small-staffed. The fast-paced and anxiousness-inducing atmosphere of an crisis space is a deterrent for many wellbeing-treatment workers.

“Many persons really don’t want to operate in hospitals,” Klibanski mentioned. “There are other [less stressful] settings where by they can function.”

The staffing shortages lengthen beyond medical professionals and nurses, and involve professionals, respiratory therapists and other tricky-to-fill employment, Klibanski said.

Much more than 50 percent a million persons in the health and fitness treatment and social providers sectors quit their positions in September — evidence, in component, of burnout related with the coronavirus pandemic — and the American Health care Affiliation says 1 in 5 medical doctors prepare on leaving the subject in two years.

The shortages have strike the health and fitness-treatment program like a tsunami, in accordance to Thomas Balcezak, main medical officer at Yale New Haven Health and fitness Medical center. He mentioned medical professionals, nurses and guidance team have experienced a change in how the public treats them as opposed with 2020.

“When covid to start with strike, there would be all of these parades earlier our medical center the place people would call wellness-treatment employees heroes,” Balcezak stated. “Now, we’re observing nurses who clearly show up in scrubs attempt to indicator up for residences remaining turned down because [management companies] really do not want individuals living there who do the job in health and fitness treatment.”

Considering that the get started of the pandemic, wellness-care staff have faced raising violence, reported Christopher S. Kang, president of the American School of Unexpected emergency Medical professionals.

In accordance to the American Healthcare facility Affiliation, 44 {bf0515afdcaddba073662ceb89fbb62b6b1bf123143c0e06b788e1946e8c353f} of nurses noted actual physical violence, and 68 p.c stated they skilled verbal abuse due to the fact the pandemic commenced.

In October, two well being-care staff were shot lifeless at Methodist Dallas Health-related Centre. Teams this kind of as the Texas Nurses Affiliation say hospitals keep on being among the most hazardous area to get the job done.

“I’ve viewed nurses and doctors be the victims of the two physical and verbal violence,” Kang explained. “It should not be a shock when they depart a field in which they are no longer revered.”

And the workload is daunting: Kang has witnessed medical professionals acquiring to evaluate individuals in waiting around rooms in the unexpected emergency ward. Patients who will need to be admitted will in some cases be pressured to linger in the ER for the reason that of insufficient nursing workers to go them to the inpatient flooring.

“It’s regrettable due to the fact it is an unpleasant problem in conditions of privacy as properly as perception,” Kang reported.

Some hospitals have set up overflow tents and activated transfer agreements with nearby facilities to regulate the surge in patients.

In the Northeast, Boston Children’s Medical center introduced in November it would postpone elective surgical procedures.

In Oct, Johns Hopkins Children’s Heart, which was managing at ability, reopened covid triage tents that ended up in the beginning utilised to control the Baltimore hospital’s overflow at the peak of the pandemic.

In November, Colorado hospitals activated transfer protocols to assist control the overflow. The Colorado Medical center Affiliation claimed the activation was simply because of “flu, COVID-19, and respiratory syncytial virus (RSV) conditions, which are tough medical center potential, specifically for the pediatric inhabitants.”

Facts shows that overcrowding in hospitals prospects to worse well being results. An analysis revealed in the Journal of Affected individual Protection identified that lengthier waiting around moments in the unexpected emergency home ended up involved with a increased likelihood of medical errors.

But not like pediatric hospitals, wherever ability troubles stem from an explosion of RSV conditions and other childhood respiratory health problems, older patients and these requiring extensive-term care deal with a various problem: They do not have any put to go when they have been discharged.

“Many people will come into the healthcare facility from a nursing residence for treatment of some kind, and then when it is time to discharge them, they just cannot go again because there is not a bed out there,” claimed Kathleen Parrinello, main operating officer at Solid Memorial Hospital in Rochester, N.Y. “And then we just cannot get people into our emergency department for the reason that our beds are stuffed with additional nursing home people than we’ve at any time had.”

The medical center bottleneck is only likely to get worse. All through the pandemic, 327 nursing residences were shut down nationwide, leading to 12,775 inhabitants to be displaced, and extra were projected to close this yr.

Parrinello reported nursing residence mattress availability in her area has absent from 4,500 to 3,000 simply because of facility closures. But most of the ability challenges can be attributed to present nursing properties not staying equipped to regulate their ability. “They do not have the personnel to continue to keep the beds open and choose in all those patients,” Parrinello reported.

Out of the approximately 1 million hospital beds in the United States, additional than 700,000 are registered with the Centers for Medicare and Medicaid Solutions. Seventy-eight percent of healthcare facility beds registered with CMS are filled with sufferers, and 4 percent of individuals are crammed with covid people, according to information from the Section of Health and Human Expert services.

And the selection of occupied beds is expected to increase as the United States heads into the late tumble and winter as coronavirus time collides with an before onset of flu conditions.

Influenza cases go on to rise, with the most up-to-date information from the CDC getting that there have been 23,000 hospitalizations and 1,300 deaths from flu so far this period.

Just about 146 million doses of flu vaccine have been administered. And 31 million men and women ages 5 and up have obtained the current coronavirus booster vaccine. But vaccines are not plenty of by yourself to deal with the crumbling crisis home infrastructure.

In November, the American Higher education of Emergency Medical professionals and 35 other wellbeing-care associations sent a letter to President Biden urging the administration to address ER staffing shortages and burnout. “Shift operate, scheduling, hazard of publicity to infectious-condition, and violence in the crisis section can all influence the psychological wellbeing and properly-staying of the medical professionals and nurses,” they wrote.

Quite a few of these very long-standing challenges ended up exacerbated by the pandemic, and the assumption was when the coronavirus surges subsided, factors would return to usual. But Klibanski, of Mass Common Brigham, stated “there is no additional standard.”

“Everything has modified, and now all these troubles at the forefront are only finding more exacerbated around time,” Klibanski explained.
